Hi everyone, my plant has been doing great for the beginning. Now the bottum older leaves are turning yellow and eventually dieing. After some research I kept reading diagnoses for plants that have the NEWER leaves turning yellow. My old ones do. The rest of the plant looks healthy and very nice green leaves. I dont want it to spread higher. Please help, thanks in advance
can't find diagnosis, please help!

if overwatered it can happen & also maybe a sign of root rot, make sure you try to get a trichoderma formula & thoroughly treat all your plants with it, i dont know your region but these guys ship worldwide, i use mycogold & trichoguard http://www.biostim.com.au/myco-gold.html you maybe able to find in your area an equal supplement
I do not over water. Im watering about every 3 days and waiting till its decently dry. Im using ffof with dynagro foilage pro. I only use the nutrients at every other watering and the ph level going in is always between 6-7.sometimes 6.2 others 6.8. They start off as tiny brown spots and then eventually turn yellow and that takes over the leaf. Starting with the buttom lower leaves.

the m
the main root rots that infect weed are pythium/fusarium/botrytis, maybe its not you overwatering but those rots came into your grow area through infected water or other means, once in your area they are very tough & will infect everything in your grow area, & they are quickly lethal to plants, maybe a step by step method you can use in a process of elimination to find an answer to your issue, i would start with a complete trichoderma treatment as stated earlier, be very careful of bringing new things into your grow area, also sciarid flies(fungus gnats) carry the above mentioned root rot diseases, are there any small type flies around the tops of your pots? if so then they are fungus gnats, which need a totally different type of treatment to deter, earlier this year i tried a new mushroom compost in my organic mix which had some very nasty bugs in it, lost a lot of good plants

I use a fabric pot..doesnt that lower my chances very much? Upon a long 10 minute stare and inspection of my plant..there were no bugs..I did notice leaves r having that "claw" tip, bending down as well as the very small tip is starting to turn yellow. What deficiency could that be?

doesnt matter what pot you use...pythium/fusarium/botrytis shows no mercy for whichever grow system you use, since your using a standard nute treatment you can count out deficiency i think & look at disease(root) to begin with, get hold of a good allround trichoderma & bacteriological treatment & apply straight away, i often give treatments of this type for much longer than required by the directions cos...it wont hurt your plants & just to make sure you kill those dreaded rots as they are stubborn & can resume their attack once treatment has finished...ive been through hell & back with these root rots...i think its a 90% chance thats what your prob is

The claw effect on your leaves indicates possible nitrogen toxicity.

good point, @antek55 are you growing in soil or potting mix? if ffof means fox farms soil then if your only watering with nutes every 3 days you will have toxic buildups, soil mixes need clear water between nute feedings
Would be helpful to have a full plant shot, looks pretty small still and a little too small for the lower leaves to die out, but it is very common and usually not a big deal, I would not do anything drastic to try and treat this you could cause more harm then good. Don't add more nutes, wouldn't be dieing off that fast and that young due to inneficency especially not in ffof. I wouldn't use any nutes with ffof on a plant that small. Use just ph'd water the next couple waterings imo.

This is a Calcium -- Magnesium problem. Your soil looks real dry as well so if I were you I would go down to your local nursery and get a soil PH and soil wet/dry meter. Your leaves are drooping when they should be standing straight up. If your soil is wet enough after the meter reading and your PH is normal at 7.0 then I would leach the soil as you may have a lockout.
